- ProjectSelect: a reusable picker that renders nothing when the projects flag is off (satisfies 'book to project hidden unless projects enabled'). - projects.service.ts: full frontend API client (list/get/create/update, overview, assign event/quote/contract, email preview + 4 actions). - Quote + contract editors carry an optional projectId (state, prefill, payload); service payload/detail types updated. - HoursSection gains a 'book to project' control; backend createEntry persists project_id (migration 118, hasColumnCached guarded).
